Surface Quality: |
S1+S2(W3.0xT2.0mm): parallel, Brewster angled,polished, uncoated,10-5 S/D,<lambda/10 @ 633nm; these 2 are for lasing surfaces
S3+S4: L(20.0+1.67)xT2.0mm; polished and AR coated; 20-10 S/D, <lambda/10 @ 633nm; these 2 are side-pumping surfaces; Parallelism >1-deg (wedged in order to avoid lasing between S3 and S4.)
S5+S6(W3.0x23.34mm): find ground 120-grit; these 2 are for mounting purpose. |
Coating: |
S1 + S2: uncoated (lasing surfaces, polished only)
S3 + S4 side-pumping surfaces: AR @ 808+/-10nm and 1064+/-10nm, 0-deg AOI, R<0.25% |
